Abstract:
An investigation on the evaporation characteristics of kerosene droplets in temperature range of473～773 K and pressure range of 1.0～4.0 MPa was performed with high-speed CCD camera system and image processing technology in the static gas environment.The effect law of ambient temperature and pressure on the evaporating process of kerosene droplets were obtained.The experimental results shows that the kerosene droplet evaporation D2 curve does not conform to the d2 law when the ambient temperature is below 573 K,and the diameter variation of the kerosene droplet conforms to the d2 law when the ambient temperature is within 673～773 K.The influence of experimental pressure on droplet evaporation is closely related to ambient temperature.When the ambient temperature is lower than 473 K,the droplet evaporation rate becomes slow with the increase of ambient pressure.When the ambient temperature is higher than 673 K,the droplet evaporation rate is increased with the increase of ambient pressure.
